[Dovecot] new configure-option --disable-index

Hello,

I don't think that dovecot will be able to find my mailboxes without 
giving it a hint, because the location is neither /var/spool/mail/%u nor 
~/Maildir :-)

It's pretty short:

disable_plaintext_auth = no
auth_verbose = yes
auth default {
   mechanisms = plain
   passdb passwd-file {
     args = /pop3/conf/pop3-auth.txt
   }

   userdb passwd-file {
     args = /pop3/conf/pop3-auth.txt
   }
}
